“…Time interval between calving to milking In agreement with previous international studies (Lomba et al, 1978;Straub and Matthaeus, 1978;Moore et al, 2005;Morin et al, 2010), colostrum IgG concentration was negatively associated with the interval from calving to colostrum collection. Corroborating the results from Straub and Matthaeus (1978), the present study failed to identify a significant difference in IgG concentration for cows milked up to 9 h post-calving, although IgG decreased thereafter.…”

“…As such, while post-parturient secretion by the mammary glands of a fluid with a much lower IgG concentration than that of colostrum contributes to lower colostral IgG with increased time from calving to milking (Morin et al, 2010), the present study does not support the view that dilution alone is responsible. Moore et al (2005) also disputed the dilution hypothesis; reporting that while colostrum collected 6, 10 and 14 h after calving from 13 Holstein cows had significantly lower IgG concentrations than colostrum collected 2 h after calving, there was no significant increase in the weight of the colostrum produced at these times. For this reason they concluded that the observed decrease in colostral IgG concentration was not due to dilution effects and suggested that perhaps colostral immunoglobulins diffuse passively into the cow's systemic circulation.…”

“…Although much research has been conducted on the factors associated with colostrum quality in cows, including parity (Pritchett et al, 1991;Gulliksen et al, 2008;Kehoe et al, 2011), breed (Muller and Ellinger, 1981), length of the dry period (Pritchett et al, 1991), time interval from calving to milking (Lomba et al, 1978;Moore et al, 2005;Morin et al, 2010) and volume of colostrum produced (Kruse, 1970;Pritchett et al, 1991), few studies have examined the factors associated with the colostrum quality of cows in seasonal, grass-based systems such as those that exist in Ireland. Moreover, only a limited number of studies have attempted to quantify the relationship between colostral IgG concentration and colostral weight (Pritchett et al, 1991;Guy et al, 1994;Baumrucker et al, 2010).…”

Transfer of sufficient immunoglobulin G (IgG) to the neonatal calf via colostrum is vital to provide the calf with immunological protection and resistance against disease. The objective of the present study was to determine the factors associated with both colostral IgG concentration and colostral weight in Irish dairy cows. Fresh colostrum samples were collected from 704 dairy cows of varying breed and parity from four Irish research farms between January and December 2011; colostral weight was recorded and the IgG concentration was determined using an ELISA method. The mean IgG concentration in the colostrum was 112 g/l (s.d. 5 51 g/l) and ranged from 13 to 256 g/l. In total, 96% of the samples in this study contained .50 g/l IgG, which is considered to be indicative of high-quality colostrum. Mean colostral weight was 6.7 kg (s.d. 5 3.6 kg) with a range of 0.1 to 24 kg. Factors associated with both colostral IgG concentration and colostral weight were determined using a fixed effects multiple regression model. Parity, time interval from calving to next milking, month of calving, colostral weight and herd were all independently associated with IgG concentration. IgG concentration decreased ( P , 0.01) by 1.7 (s.e. 5 0.6) g/l per kg increase in the colostral weight. Older parity cows, cows that had a shorter time interval from calving to milking, and cows that calved earlier in spring or in the autumn produced colostrum with higher IgG concentration. Parity ( P , 0.001), time interval from calving to milking ( P , 0.01), weight of the calf at birth ( P , 0.05), colostral IgG concentration ( P , 0.01) and herd were all independently associated with colostral weight at the first milking. Younger parity cows, cows milked earlier post-calving, and cows with lighter calves produced less colostrum. In general, colostrum quality of cows in this study was higher than in many previous studies; possible reasons include use of a relatively low-yielding cow type that produces low weight of colostrum, short calving to colostrum collection interval and grass-based nutritional management. The results of this study indicate that colostral IgG concentration can be maximised by reducing the time interval between calving and collection of colostrum.

“…Colostrum is characterised by its very high concentration of immunoglobulin G (IgG), which is of particular importance to the neonate, whose gut, immediately following parturition, allows the passage of large immunoglobulins, thereby conferring passive immunity (Marnila and Korohnen 2002;Tsioulpas et al 2007;Stelwagen et al 2009). It is essential that the newborn calf receives an adequate supply of colostrum as both the concentration of immunoglobulins and permeability of the gut decrease rapidly over the first 24 h following parturition (Weaver et al 2000;Moore et al 2005). In addition, colostrum intake influences metabolism, endocrine systems and the nutritional state of neonatal calves (Guilloteau et al 1997;Blum and Hammon 2000a, b) and stimulates the development and function of the gastrointestinal tract (Hadorn et al 1997;Guilloteau et al 1997;Buhler et al 1998;Blum and Hammon 2000a, b).…”

Colostrum is the initial milk secreted by mammals following parturition, the composition and physicochemical properties of which are highly dynamic and variable. The composition and physicochemical properties of colostrum during the initial postpartum period has not been systematically reviewed for many years, although the topic remains of interest both to milk producers and processors. In this article, the current understanding of the composition of colostrum, i.e. carbohydrates, proteins, growth factors, enzymes, enzyme inhibitors, nucleotides and nucleosides, cytokines, fats, vitamins and minerals, is reviewed. In addition, the physicochemical properties, i.e. pH and buffering capacity, colour, density and specific gravity, osmotic pressure, somatic cell count, properties of casein micelles, ethanol stability and rennet coagulation properties are discussed, as well as the effects of heat-treating colostrum.

“…Diversos estudios han mostrado que el calostro de las novillas de primer parto presenta una concentración de Igs considerablemente menor que el de vacas con más lactancias y que a su vez, dicha concentración se incrementa conforme aumenta el número de partos (Moore et al, 2005;Gulliksen et al, 2008;Kehoe et al, 2011). Una razón es que las novillas han sido expuestas a antígenos por menor tiempo que vacas con más lactancias; además, el mecanismo de transporte de Igs hacia la glándula mamaria también puede estar menos desarrollado que el de vacas adultas (Devery y Larson, 1983 Cuadro 2.…”

RESUMENCaracterización de la transferencia de inmunidad pasiva en terneras de lechería. El objetivo del presente trabajo fue determinar la transferencia de inmunidad pasiva en terneras de lechería en Costa Rica. Los datos presentados corresponden a medidas de proteína sérica total (PST) obtenidas en el periodo comprendido entre los años 2010 y 2013, durante los meses de agosto a noviembre en 50 fincas lecheras. Se evaluaron 2500 terneras nacidas de vacas Holstein, Jersey, cruce Holstein×Jersey y otras. Para fines del presente estudio, se consideró una falla en la transferencia de inmunidad pasiva (FTIP) cuando la concentración de PST fue menor a 5,5 g/dl. La concentración de PST varió entre 2,0 y 10,0 g/dl, con un promedio de 5,9 g/ dl. De todos los animales muestreados un 38,8% presentaron FTIP. Los animales provenientes de la raza Jersey y del cruce Holstein×Jersey obtuvieron una concentración de PST significativamente mayor (P<0,05) a los de las razas Holstein y otras. Al considerar el número de parto de la madre, no se encontraron diferencias significativas en la concentración de PST de las crías. Las crías de vacas de primer parto presentaron la menor proporción de animales con FTIP. La concentración de PST varió significativamente (P<0,05) entre las terneras que permanecieron con la madre y las que fueron alimentadas con biberón, y la proporción de animales con FTIP fue mayor cuando estos permanecieron con la madre (44 vs. 33%).Palabras clave: proteína sérica total, calostro, inmunoglobulinas, ganado de leche.
